//!
//! # Usage example
//! ```rust
//! use ecs_types::types::Timestamp;
//! use ecs_types::*;
//! use serde_json::json;
//!
//! let now: Timestamp = chrono::offset::Local::now().into();
//! let mut base = Base::new(now.clone());
//! let mut file = File::default();
//! file.set_name("readme.txt".into());
//! file.set_mtime(now);
//!
//! base.with_file(file);
//! println!("{}", serde_json::to_string_pretty(&json!(base)).unwrap() );
//! ```
//!
//! creates the following result:
//! ```json
//! {
//! "@timestamp": 1669822098181,
//! "file": {
//! "attributes": [],
//! "mtime": 1669822098181,
//! "name": "readme.txt"
//! },
//! "tags": []
//! }
//! ```
